Thank god for copper
This is a treasure trove of information on our most valuable resource COPPER! from the blasting (is it neccesary to use 15 sticks of dynamite in a tube then use a rod to ram it in?) to the dumping on to railcars, to the refining, and finally to the smelting, the film is never boring, although the topic may put some people off.
